Predict the product that is formed when methyl 2-(3-oxocyclohexyl)acetate undergoes a reaction with LiAlH4.
Find the formal concentration of the acid in each phase when 100 mL of 0.10 M aqueous acid is extracted with 35 mL of octanol at (a) pH 4.00 and (b) pH 9.00.
Calculate the heat absorbed by 15.0 g of water to raise its temperature from 20.0oC to 50.0oC at constant pressure. The specific heat of water is 4.18 J/g.oC
How many milliliters of 0.5 mg/mL BSA will you use in each tube to get the range of 0-50 micrograms that you want?
A solution is prepared by mixing 75.0 mL of 0.030 M BaCl2 and 250. mL of 0.040 M K2SO4. What are the concentrations of barium and sulfate ions in this solution? Assume only SO42- ions (no HSO4-) are present.
Consider the same dilution above for an SN1 reaction. Would the time required for 95% for the starting material to react change as a result of this dilution?
calculate the heat in joules released by the dissolving salt. Assume that the specific heat of the solution is the same as thar of pure water(4.184J/g- celcius) and that the calorimeter is perfect.
The equilibrium constant Kp is measured (at an unspecified temperature) to be 0.66 for the reaction:
A solution of ethanol (C2H6O) in water is sometimes used as s disinfectant. 1.00 L of this solution contains 553 g or ethanol and 335 g of water. What is the mole fraction of ethanol in this solution.
H2s and H20 have similar structures and their central atoms belong to the same group. Yet H2S is a gas at room temperature and H20 is a liquid. Use bonding principals to expalin why this is.
